Influence of Heat Treatment on Residual Stress Formation in the Wear-Resistant Steel 60-Steel 15-Steel 60 Bimetal Material

摘要

We investigate the influence of heat treatment on the residual stress formation in the 7-mm-thick three-layer wear-resistant bimetal steel 60–steel 15–steel 60 sheet produced by hot rolling. We determine that the thickness of the cladding layers is ≈2–2.1 mm, the thickness of the main layer is ≈2.8–3 mm, and the transition zone width is ≈0.5–0.8 mm. We show that the most favorable distribution of the residual stresses and the set of mechanical properties will achieved after quenching and tempering at 300°C.
